[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0040] In related technologies, protective cases are typically used for battery transportation. The batteries are placed inside these cases and then mounted on transport vehicles to facilitate transport. However, in these technologies, batteries are easily damaged during transportation due to collisions, drops, or other factors, posing safety hazards.

[0041] Based on this, the present invention provides a protective device for batteries. By placing the battery in the accommodating cavity of the protective body and setting a stabilizing structure on the protective body, the stabilizing structure has a connecting part that can be detachably connected to the compartment of the transport vehicle. During battery transportation, the protective body and the battery can be fixed to the compartment through the connecting part, thereby avoiding damage to the battery due to collisions, drops, etc. during transportation to a certain extent.

[0042] The battery protection device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0043] Reference Figures 1 to 8 As shown, this embodiment provides a battery protection device (hereinafter referred to as the protection device), wherein the battery 20 can be a lithium-ion battery, or the battery 20 can also be a sodium battery, lead-acid battery, etc. The protection device 10 can be used, for example, during the transportation of the battery 20.

[0044] For example, when transporting the battery 20, it is necessary to use a transport vehicle (not shown in the figure) with a compartment in which the protective equipment 10 can be placed.

[0045] The protective equipment 10 includes a protective body 1 and a stabilizing structure 2.

[0046] Reference Figures 1 to 3 As shown, the protective body 1 has a cavity 11 for placing the battery 20. The stabilizing structure 2 is detachably connected to the protective body 1. The stabilizing structure 2 has a connecting part 221 for detachably connecting to the carriage, so as to at least fix the protective body 1 to the carriage.

[0047] The battery protection device provided in this embodiment includes a protective body 1 and a stabilizing structure 2. The protective body 1 has a cavity 11 for placing the battery 20. The stabilizing structure 2 is detachably connected to the protective body 1 and has a connecting part 221. The connecting part 221 is detachably connected to the cargo compartment of a transport vehicle to at least fix the protective body 1 to the cargo compartment. This configuration, by placing the battery 20 in the cavity 11 of the protective body 1, provides a certain degree of protection against impacts. This can, to some extent, prevent the battery 20 from being damaged due to accidental drops or collisions with the external structure of the protective device 10 during transportation or loading / unloading, thereby ensuring the safety of the battery 20 during subsequent use.

[0048] Meanwhile, since the connecting part 221 on the stabilizing structure 2 is detachably connected to the cargo compartment of the transport vehicle, it is easy to fix the protective body 1 to the cargo compartment through the stabilizing structure 2, thereby securing the battery 20. The battery 20 is stored stably on the transport vehicle, which can further prevent the battery 20 from accidentally falling or colliding with the external structure of the protective equipment 10 in scenarios such as bumpy roads or sudden braking of the transport vehicle. This improves the protection effect of the battery 20 and eliminates the safety hazards of the battery 20 during transportation to a certain extent, thus helping to further ensure the safety of the battery 20 in subsequent use. Furthermore, if either the protective equipment 10 or the transport vehicle is damaged, the damaged part can be replaced, thus avoiding the scrapping of the entire protective equipment 10 and the transport vehicle, which helps to save maintenance and usage costs. Moreover, when the battery 20 needs to be unloaded from the cargo compartment after transportation, the connecting part 221 can be directly separated from the cargo compartment, thus ensuring the continuous protection of the battery 20 by the protective body 1.

[0049] Furthermore, since the stabilizing structure 2 is detachably connected to the protective body 1, when fixing the battery 20 to the vehicle compartment via the protective device 10, the stabilizing structure 2 and the protective body 1 can be separated first, then the stabilizing structure 2 can be fixed to the vehicle compartment, and the battery 20 can be placed in the receiving cavity 11 of the protective body 1. After that, the protective body 1 containing the battery 20 can be connected to the stabilizing structure 2. Compared with the scheme where the stabilizing structure and the protective body are fixedly connected, this makes it more convenient and flexible to fix the battery 20 to the vehicle compartment via the protective device 10. In addition, since the stabilizing structure 2 and the protective body 1 are detachably connected, if either the stabilizing structure 2 or the protective body 1 is damaged, only the damaged part needs to be replaced. This can avoid the scrapping of the entire stabilizing structure 2 and the protective body 1 to a certain extent, which helps to save maintenance and usage costs.

[0050] In some embodiments, refer to Figures 1 to 3 As shown, the protective body 1 includes a hollow protective shell 12 and a cover 13. The cover 13 is connected to the protective shell 12 and together define the accommodating cavity 11.

[0051] In this way, the cooperation between the cover 13 and the protective shell 12 can improve the protection effect of the battery 20 to a certain extent and further realize the protection of the battery 20 against bumps and knocks.

[0052] In practice, the protective shell 12 can be connected to the stabilizing structure 2.

[0053] For example, refer to Figures 1 to 3 This allows the cover 13 to be rotatably connected to the protective shell 12 via a hinge.

[0054] In some embodiments, refer to Figures 1 to 3 As shown, the protective housing 12 is provided with a buckle 121, and the cover 13 is provided with a buckle hole 131 into which the buckle 121 can be inserted and engaged.

[0055] This makes the connection between the protective shell 12 and the cover 13 convenient and reliable, which helps to ensure the protective effect of the protective body 1 on the battery 20 and further realizes the anti-collision protection of the battery 20.

[0056] Of course, a snap hole 131 can also be provided on the protective housing 12, and a buckle 121 can be provided on the cover 13.

[0057] In addition, the housing and cover 13 can be detachably connected by means of screws or the like.

[0058] In some embodiments, flame-retardant components are provided on at least part of the inner wall surface of the accommodating cavity 11. This can, to a certain extent, prevent the flame from spreading through the protective body 1 when the battery 20 in the accommodating cavity 11 spontaneously combusts due to a short circuit or other reasons. This can provide isolation protection for the remaining batteries 20 located around the spontaneously combusting battery 20.

[0059] In some embodiments, the flame retardant component includes a polycarbonate board (PC) component, which can prevent the spread of flames when the battery 20 spontaneously combusts, thereby isolating and protecting the remaining batteries 20 around the spontaneously combusting battery 20.

[0060] For example, flame-retardant components can be flame-retardant plates, flame-retardant blocks, etc.

[0061] In addition, in other embodiments, the flame-retardant component may also be a mica component, etc.

[0062] In some embodiments, the carriage includes a metal carriage, as shown in the reference. Figures 4 to 5 As shown, the connecting part 221 includes a magnet that can magnetically engage with the carriage.

[0063] The protective equipment 10 can be connected to the carriage by magnetic attraction between the connecting part 221 and the carriage. When it is necessary to unload the protective equipment 10 from the carriage, the connecting part 221 can be disengaged from the carriage. The connection between the protective equipment 10 and the carriage is simple and convenient, and no other third-party medium or tool is required to connect or detach the protective equipment 10 from the carriage, resulting in high connection efficiency. Moreover, this can also avoid damaging the carriage structure by drilling holes in it to a certain extent.

[0064] Of course, in other embodiments, the connecting part 221 may include a first connecting hole, and a second connecting hole may be provided on the carriage, so that the protective device 10 is connected by screws or the like passing through the first connecting hole and the second connecting hole.

[0065] Specifically, the magnet can be positioned on the outside of the stable structure 2 to facilitate the attraction between the magnet and the carriage.

[0066] For example, the carriage can be made of iron or steel.

[0067] In some embodiments, refer to Figures 4 to 5As shown, the stabilizing structure 2 includes a base 21 and an adjusting member 22. The base 21 has a power supply and a first plug-in portion 211 electrically connected to the power supply. The magnet includes an electromagnet mounted on the adjusting member 22. The adjusting member 22 also has a second plug-in portion 222 electrically connected to the electromagnet and capable of mating with the first plug-in portion 211. The adjusting member 22 can move relative to the base 21 to adjust the insertion state of the first plug-in portion 211 and the second plug-in portion 222. The insertion states include: the first plug-in portion 211 and the second plug-in portion 222 are inserted; the first plug-in portion 211 and the second plug-in portion 222 are disengaged.

[0068] The movement of the adjusting member 22 can be either moving or rotating, as long as the movement of the adjusting member 22 can adjust the insertion state of the first insertion part 211 and the second insertion part 222.

[0069] This configuration facilitates the movement of the control adjustment component 22, allowing the first insertion part 211 and the second insertion part 222 to be inserted, thereby supplying power to the electromagnet and making it magnetic so that it can be attracted to the carriage or other locations to fix the protective equipment 10. Alternatively, the first insertion part 211 and the second insertion part 222 can be disengaged so that the electromagnet loses power and its magnetism disappears, making it easy to unload and move the protective equipment 10 from the carriage or other locations, thus making it convenient to use.

[0070] For example, the power source could be a rechargeable battery or a dry cell battery.

[0071] Among them, electromagnets can be electromagnet discs, electromagnet blocks, etc.

[0072] For example, the first plug portion 211 can be an electrical port, and the second plug portion 222 can be a plug. Alternatively, the first plug portion 211 can be a plug, and the second plug portion 222 can be an electrical port.

[0073] For example, the protective body 1 can be detachably connected to the base 21. For instance, threaded holes can be provided on the base 21, allowing the base 21 to be connected to the protective body 1 via bolts passing through the threaded holes. The threaded holes can be four located at the corners of the base 21 to improve the stability of the connection.

[0074] Of course, in other implementations, the protective body 1 can also be connected to the adjusting component 22.

[0075] In some embodiments, refer to Figures 4 to 6 As shown, a guide structure is provided between the adjusting member 22 and the base 21 to guide the movement of the adjusting member 22.

[0076] This configuration allows the adjusting member 22 to move along a preset path, thereby improving the stability of the adjusting member 22 during movement and further improving the stability of the insertion state between the first insertion part 211 and the second insertion part 222.

[0077] In some embodiments, refer to Figures 4 to 6 As shown, the guide structure includes a guide protrusion 223 disposed on the adjusting member 22 and a guide groove 212 disposed on the base 21. The guide protrusion 223 extends into the guide groove 212 and can slide along the guide groove 212.

[0078] By sliding the guide protrusion 223 along the guide groove 212, the movement of the adjusting member 22 can be guided. The guide structure is simple and has a good guiding effect, which can further improve the stability of the adjusting member 22 during movement.

[0079] For example, the guide protrusion 223 can be a guide block or a guide post, etc.

[0080] There can be two guide grooves 212, which are symmetrically arranged on the base 21, and two guide protrusions 223, which correspond one-to-one with the guide grooves 212.

[0081] Of course, in other embodiments, a guide groove may be provided on the adjusting member 22 and a guide protrusion may be provided on the base 21.

[0082] Specifically, when the adjusting member 22 can move relative to the base 21, the guide groove 212 is a straight groove; when the adjusting member 22 can rotate relative to the base 21, the guide groove 212 is an arc-shaped groove.

[0083] Alternatively, a guide sleeve can be provided on the base 21 and fitted around the outer periphery of the adjusting member 22, so that the adjusting member 22 can slide along the axial direction of the guide sleeve, and the inner wall of the guide sleeve forms a guiding structure.

[0084] In some embodiments, refer to Figures 4 to 5 As shown, the base 21 is provided with a mounting groove 213, and the adjusting component 22 is located in the mounting groove 213 and is flush with the opening of the mounting groove 213.

[0085] The mounting groove 213 allows for the positioning of the adjusting component 22 and also guides its movement to some extent, thus improving its stability during movement and consequently enhancing the stability of the connection between the first insertion part 211 and the second insertion part 222. Furthermore, the mounting groove 213 saves space occupied by the stabilizing structure 2, reducing the size of the protective equipment 10 and facilitating handling and loading. In addition, since the adjusting component 22 is flush with the opening of the mounting groove 213, the contact area between the stabilizing structure 2 and the vehicle body is increased, further improving the stability of the protective equipment 10.

[0086] For example, the mounting groove 213 can be adapted to the outer contour of the adjusting member 22 to improve the positioning effect. For instance, the outer contour of the adjusting member 22 can be approximately rectangular, in which case the mounting groove 213 is a rectangular groove.

[0087] In some embodiments, refer to Figures 4 to 8 As shown, the protective device 10 also includes a positioning structure 3 to detachably position the adjusting member 22 on the base 21 when the adjusting member 22 moves to the first insertion part 211 and the second insertion part 222 are inserted.

[0088] This facilitates the insertion of the first connector 211 and the second connector 222. When the electromagnet is magnetic, the positioning structure 3 positions the adjusting member 22 on the base 21, preventing accidental movement of the adjusting member 22 relative to the base 21. This ensures reliable engagement between the electromagnet and the carriage, improving the stability of the protective equipment 10 when stored in the carriage. Simultaneously, this also facilitates the removal of the adjusting member 22 from the base 21, providing convenience for subsequent maintenance and repair of the electromagnet.

[0089] For example, when it is necessary to separate the first insertion part 211 and the second insertion part 222, the positioning structure 3 can be used to cancel the positioning of the adjusting member 22 on the base 21, and then the adjusting member 22 can be moved.

[0090] In some embodiments, refer to Figures 4 to 8 As shown, the positioning structure 3 includes a first locking body 31 disposed on the base 21 and a second locking body 32 disposed on the adjusting member 22, the first locking body 31 and the second locking body 32 being engaged and connected.

[0091] This allows the adjusting component 22 to be positioned on the base 21 by engaging the first locking assembly 31 and the second locking assembly 32, and the positioning of the adjusting component 22 can be canceled by disengaging the first locking assembly 31 and the second locking assembly 32. It is simple and convenient to use, and the positioning effect is reliable.

[0092] In some embodiments, refer to Figures 6 to 8As shown, the first card assembly 31 includes a card slot, and the second card assembly 32 can extend into and engage within the card slot through the opening of the card slot. In this way, by extending the second card assembly 32 into the card slot, the second card assembly 32 and the first card assembly 31 can be matched and engaged, making it convenient to use.

[0093] In some embodiments, refer to Figures 6 to 8 As shown, the base 21 includes a seat body 214 and positioning members 215 disposed on the base 21. There are two positioning members 215, which are arranged at intervals on the seat body 214 to define the slot together with the seat body 214.

[0094] This configuration can further improve the positioning effect of the adjusting member 22, and further ensure the positional stability of the adjusting member 22 relative to the base 21 when the first insertion part 211 and the second insertion part 222 are inserted, which in turn helps to further ensure the stable connection of the protective equipment 10 on the carriage.

[0095] Of course, a card slot can also be directly made on the base 21.

[0096] In some embodiments, refer to Figures 6 to 7 As shown, a guide portion 216 is provided on the positioning member 215. The guide portion 216 is used to guide the second card assembly 32 when it extends into the card slot.

[0097] In this way, the guide part 216 can guide the second locking body 32 to extend into the slot, thereby improving the convenience and efficiency of the second locking body 32 engaging with the slot, and thus improving the positioning efficiency of the adjusting member 22 on the base 21.

[0098] For example, the guide portion 216 may be a chamfer provided on the positioning member 215, or it may be a guide slope provided on the positioning member 215, etc.

[0099] In some embodiments, refer to Figures 6 to 8 As shown, the second engaging body 32 includes an engaging body 321 and at least one elastic engaging component 322. The engaging body 321 is disposed on the adjusting member 22, and the elastic engaging component 322 is connected to the adjusting member 22 and can move relative to the engaging body 321 to extend into or move out of the slot.

[0100] This allows the elastic engaging component 322 to deform under its own elasticity, making it easier for the elastic engaging component 322 to engage or disengage from the slot, making it more convenient to use and with higher engaging efficiency.

[0101] Of course, in other implementations, the second locking body 32 can also be a rigid locking block, etc., and the insertion into or removal from the locking slot can be achieved by the movement of the rigid locking block relative to the adjusting member 22.

[0102] Reference Figure 8 For example, there can be two elastic locking components 322, or the two elastic locking components 322 can be set opposite to each other.

[0103] Continue to refer to Figure 8 For example, when there are two elastic engaging components 322, the connector 328 can be placed between the two elastic engaging components 322.

[0104] In some embodiments, refer to Figure 8 As shown, the elastic engaging assembly 322 includes an elastic element 323 and an engaging element 324. A connecting member 328 is provided on the engaging body 321. At least a portion of the connecting member 328 is located on one side of the elastic element 323 along its deformation direction. One end of the elastic element 323 is connected to the engaging body 321 via the connecting member 328, and the other end of the elastic element 323 is connected to the engaging element 324, so that the engaging element 324 can move relative to the engaging body 321 under the action of the elastic element 323 to extend into or move out of the slot. The deformation direction of the elastic element 323 can, for example, be... Figure 8 The X-direction in the middle.

[0105] By deforming the elastic element 323, the engaging element 324 moves relative to the engaging body 321 to engage with or disengage from the slot. The engagement is convenient and, compared to solutions that include silicone parts such as rubber parts in the elastic engaging component, this method improves the ease of engagement between the elastic engaging component 322 and the slot while ensuring the engagement effect between the elastic engaging component 322 and the slot. The engagement stability is high, which ensures the positioning effect of the adjusting element 22 on the base 21. This, in turn, helps to ensure the stable insertion of the first insertion part 211 and the second insertion part 222, further improving the stability of the protective equipment 10 on the carriage.

[0106] For example, refer to Figure 8 The connector 328 can be a connecting plate or a connecting column, etc.

[0107] In some embodiments, refer to Figure 8 As shown, the engaging body 321 has a receiving cavity 325, and the engaging member 324 slides in cooperation with the cavity wall of the receiving cavity 325 to guide the movement of the engaging member 324.

[0108] This improves the stability of the movement of the locking component 324, thereby improving the ease of locking or disengaging the locking component 324 from the slot. This, in turn, improves the positioning efficiency of the adjusting component 22 on the base 21 and the efficiency of disengaging the adjusting component 22 from the base 21, making it more convenient to use.

[0109] For example, refer to Figure 8 For example, a groove 329 can be provided on the cavity wall of the receiving cavity 325, and the engaging member 324 can extend into the groove 329 and move along the groove 329.

[0110] In some embodiments, refer to Figure 8 As shown, there are at least two elastic elements 323, and at least two elastic elements 323 are arranged at intervals between the engaging element 324 and the engaging body 321.

[0111] This configuration allows for elastic connection between the engaging member 324 and the connecting member 328 at multiple locations, which helps ensure the connection stability between the engaging member 324 and the connecting member 328. This, in turn, guarantees the engaging effect between the engaging member 324 and the slot, further improving the positioning effect of the adjusting member 22 on the base 21. Simultaneously, the multiple elastic members 323 also help increase the movement speed of the engaging member 324 under the reset drive of the elastic members 323, thereby further improving the engaging efficiency between the engaging member 324 and the slot, and thus further enhancing the positioning efficiency of the adjusting member 22.

[0112] In some embodiments, refer to Figure 8 As shown, the locking member 324 includes a locking part 326 and a gripping part 327 for holding. The locking part 326 is connected to the gripping part 327 and is used to extend into the locking slot.

[0113] This design facilitates the movement of the entire engaging component 324 relative to the engaging body 321 by holding the gripping part 327, so that the engaging part 326 can extend into the slot and engage with it, making it convenient to use.

[0114] In a specific implementation, the engaging part 326 can be an engaging block or an engaging post. The gripping part 327 can be a gripping block or a gripping post, etc.

[0115] For example, the engaging portion 326 and the gripping portion 327 can be integrally formed, so that the engaging part 324 has high structural strength, thereby ensuring the engaging effect of the engaging portion 326 and the slot, and facilitating subsequent assembly.
